The singer, who dated the cyclist during two of his seven Tour de France wins, was "in the room" with Lance while he discussed covering up his drug use with teammate Frankie Andreu.

Andreu's wife, Betsy, said the following in an affidavit while under oath:

"His girlfriend at the time, Sheryl Crow, was in the room and I felt uncomfortable talking about this in front of her so I did not say much ...Frankie did not not want to discuss this in front of her."

Betsy says Armstrong tried to convince her to retract her claim that he told doctors treating him for cancer that he’d taken steroids, human growth hormone, cortisone and EPO.

In a recent interview with ET, Crow opened up about Armstrong saying:

"I think that honesty is always the best bet and that the truth will set you free. It must be really hard to walk around knowing you are not telling the truth about something. So I always contend that the truth is the best way to go. I know how hard he worked to win those titles, and you know, it was hard to watch. I felt bad. I felt bad for him, I felt bad for his family, and I kinda felt like the rest of America. He is a hero that we watched and looked up to and admire.”
